THINKS GO BETTER WITH ADDBLUE DEF

 Addblue Def is a high specification solution and is manufactured to the DIN 70070 and ISO 22241 standards.

Simply put, Addblue Def is a 32.5% solution of urea in deionised water and is required by many commercial vehicles operating on the European roads.  Addblue Def  is essential for the correct operation of an advanced pollution control technology installed in the exhaust system called Selective Catalytic Reduction or SCR. Unlike diesel, Addblue Def is a clear, non-toxic liquid that is safe to handle and does not damage the environment.  Addblue Def  is not a fuel or a fuel additive.

 Addblue Def is a high specification solution and is manufactured to the DIN 70070 and ISO 22241 standards.

Currently, Addblue Def is required by the majority of heavy duty diesel vehicles (trucks, buses and coaches) purchased after October 2006.

In order to meet the Euro IV and V emissions limits, all of the major European truck makers, to a greater or lesser extent, offer SCR equipped vehicles. However, MAN and Scania have a firm focus on an alternative technology called EGR that does not require the use of Addblue Def and have equipped the majority of their model ranges accordingly.

It is important to ensure that the vehicles remain supplied with Addblue Def, as an on-board policing system will enforce a torque penalty if the AdBlue® tank is empty. This is to ensure that the vehicles NOx emissions remain below the legal limit.

SCR, or Selective Catalytic Reduction, is an emissions control technology first employed on coal-fired power stations to clean oxides of nitrogen (NOx) from the exhaust gasses. In 2006, the technology successfully crossed into the European heavy-duty diesel market, where it enabled trucks to meet the Euro IV and V limits.

An SCR system uses AdBlue® and a vanadium or base metal catalyst mounted in the vehicle's muffler to reduce NOx to water vapour and atmospheric nitrogen. This reaction takes place downstream of the engine in the exhaust system and is known as "after-treatment". Unlike the alternative EGR technology - championed by MAN and Scania - SCR tackles the problem outside of the engine and has the potential to achieve >80% NOx reduction rates, allowing the engine to be tuned for maximum efficiency. Having the engine set up for maximum efficiency allows for an estimated fuel saving of 3-5%, giving operators the opportunity to save thousands on their annual diesel fuel bills.

Addblue Def can be purchased by the haulier on the road at a truck stop, service station or manufacturer dealership. It is also possible to arrange for a supply of Addblue Def® direct to the haulier's base of operations. You can use Find Addblue Def®.com to find the nearest AdBlue® supply point and information about home base Addblue Def® supply. FindAdBlue.com has details of over 10,000 AdBlue® supply points throughout Europe.

While the price of Addblue Def® is lower when purchased in bulk at the home depot, this method can incur costly installation and equipment fees. In fact, some operators prefer the convenience of roadside Addblue Def® refilling. Indeed, Addblue Def® refilling is often linked to the operator's diesel refuelling strategy.

Addblue Def® is used by the SCR system at a rate equivalent to 5% of diesel consumption and is currently less than half the price of diesel, per litre.
